To all whom it may concern:

Be it known that I, FRED L. OLIVER, of Friendship, in the county ofAllegany and State of New York, have invented a new and ImprovedMilk-Strainer, of which the follow ing is a specification:

The strainer is constructed of funnel shape, adapted to cover the entiretop or opening of a can or other vessel, and is constructed with anannular flange to fit within the mouth of the can.

wire-gauze, above which is placed a removable diaphragm ofperforatedsheet metal, to protect the gauze and to arrest the largermaliters which are to be strained out of the m1 In the accompanyingdrawing, Figure 1 is a plan or top view of the device. Fig. 2 is avertical section of the same as applied to a milk-can in readiness forthe reception of milk. Fig. 3 is a vertical section, showing thestrainer in its reversed position to constitute a cover. Fig. 4 is aperspective view of the removable preliminary strainer.

A may represent a milkcan of common form. B (J represent, respectively,the body and neck or nozzle of a funnel, at the bottom of which issecured a web or sheet, D, of wiregauze. E represents an annular flange,permanently secured to the under side of the funnel B, and adapted tofit within the mouth or top of the can A. The removable preliminarystrainer (shown in Fig. 4, and in position in Figs. 1 and 2) consists ofa plate, F, of perforated sheet metal, a flange, G, attached thereto andsupporting it at the necessary height above the gauze D, and a handle,H, for removing and applying the said preliminary strainer. It will beseen that the parts are so proportioned that the preliminary strainer Fis supported within the neck or nozzle 0 of the funnel, at a sufficientdistance below the outer margin thereof to prevent the milk from bein gcarried up the opposite side of the inclined funnel B when poured infrom one side. This dispenses with the necessity of guards or The funnelterminates below in a cylindrical nozzle covered at bottom with checkssometimes provided for this special purpose. The perforatedsheet-inetalstrainer F arrests all the larger particles which are to bestrained out of the milk, and protects the wire-gauze D from sudden orheavy pressure when the milk is poured into the strainer. The wire-gauzeD is thus preserved from injury, and, receiving the milk uniformly overits entire surface, passes the same into the can with great rapidity.

I am thus enabled to use a wire-gauze strainer sufficiently fine tothoroughly cleanse the milk, while it does not impede the strainingoperation inconveniently.

The milk having been strained into the can, it is important that itshall be fully exposed to the air while parting with its animal heat. Topermit the necessary ventilation for this purpose, and, at the sametime, to protect the milk in the interior of the can from dust andimpurities, the strainer is employed as a cover, in the mannerillustrated in Fig. 3. The fine wire-gauze D afl'ords free and thoroughventilation, while, at the same time, it prevents the entrance of theslightest dust. Any dust or other impurities which may settle on thegauze D or other part of the bottom of the inverted strainer are, ofcourse, readily washed off when the strainer is removed for the purposeof placing the permanent cover on the can.

The flange E fits the mouth of the can tightly enough to prevent theloss of milk in the event of upsetting or sudden movement of the can.

The following is claimed as new:

1. A funnel-shaped strainer, B O D, with an annular flange, E, attachedto its under side, and tightly fitting the interior of the mouth of thecan A, as and for the purpose set forth.

2. The removable preliminary strainer F G H, constructed as described,and inserted below the margin of the cylindrical neck C of the funnel,for the purposes set forth.
